I should have posted this with the images. Richard

Folks, The DSO TFD Array recorded some very faint Io-B early on 23 March 2025.? You will need to squint and stand on your left leg to see this, but all (except possibly the second [B] image) have

After a promising start to the morning with a few well-defined teepees, the airglow completely disappeared before midday.* From this point on, band noise was low as it usually is in the late evening,
